Palm Pilot user interface
The PhatBox may be for sale at www.phatnoise.com. Unfortunately, the new PhatBoxes lack the serial port to duplicate the Palm portion of this install. You can use only a compatible CD changer controller to use the PhatBox (either in your head unit or RF modulator/controller). If you have an older box, and would like to duplicate my Palm set-up, or any box and would like a Becker set-up, email me at email@example.com, and we'll see if we can get it working in your car.
I wanted an mp3 player which had the following qualities:
I found PhatNoise in Dec. 2000. They were working on exactly what I wanted (except without an ethernet jack). I quickly got a job there, and started secretly working on compatibility with my head unit. Mid-2001 I installed a first-generation PhatBox, using only a Palm as control, and the AUX input of the stereo. In the beginning of 2002, after much help from many of the guys at PhatNoise, I finally got the PhatBox working with the CD changer interface. The setup also retains the Palm as an auxillary control, useful for a passenger wanting to find songs. The box plugs into the cd changer control cable via a PhatBox-Sony adapter cable (The Porsche Becker unit acts very similar to a Sony unit). I needed a female-female Unilink gender changer to plug the two cables together. Audio goes through the separate RCA cables. Then a serial cord was dropped into the cabin on the right side of the center storage trays. I can then plug any number of serial devices (palm pilot, laptop) into to cable to control the box, or tuck the cable away when not in use.
The PhatBox has a removable hard drive which is plugged into a PC via a USB dock. Copying over files and creating playlists is quite simple. I'm still waiting for a good wireless (802.11) solution where I wouldn't have to take anything out of my car.
The installation was done by Paris Audio. This is THE place to go for audio and performance upgrades for your Porsche. They were also helpful with test units to get this working.
The PhatBox is mounted in the front trunk next to the amp, where a CD
changer would go.

The cables are nicely tucked away. pic
The serial cable drops into the passenger footwell. pic
I usually leave the Palm in the tray while driving for easy access to the hard buttons, which are programmed for disc/track up/down. pic
NEW - I swapped out the red shell for a silver shell. It's still the same old "red" PhatBox with a serial port, just a different shell. pic
Head Unit Interface
The PhatBox acts just like a cd changer would. Buttons 1-10 go to my different playlists, and the track knob (and entering a track directly) go to the different songs in the playlist. Update: I have upgraded the controls to use the PhatNoise SSA Interface. So when I want to listen to a particular song, I just press 4, hear "Now browsing artists, the current artist is so-and-so", begin a fast forward and hear the letters of the alphabet spoken, end fast forward, and am on the first artist of that letter. I can then switch forward to the artist I want to hear, then the song, all without taking my eyes off the road.
The box playing "Disc 2, Track 99".
The head unit and Palm displays are synchronized. Here's the box playing the same D2/T99, with the Palm in "CD Changer" mode. pic
Disc 2, Track 100, with the Palm in "Title" mode. Note that the head unit can only display 2 digits for track and 1 for disc. The full title of the song, and disc/track number are scrolling by on the Palm. pic
CD Changer style controls
Next/Previous Track, Next/Previous Disc, Play, Pause, and Refresh Display buttons. The display shows the disc/track/time, playlist name, and track name.
List of all "discs" and "tracks"
You can scroll up and down to see all the songs in all playlists. A file will start playing when selected. In both views, the "hard" buttons on the bottom are programed for track up/down (up/down buttons), and disc up/down (address book and to-do).
The application now hooks into the Palm search function. Using the standard Palm search method, you can search for songs, then click on them to start playing.
